ASTM F1140: Burst and Creep Testing

ASTM F1140 package testing explains the ability of packages to withstand internal pressurization. As an ISTA and ISO 17025 certified lab, we realize the importance of ASTM burst and creep testing. Meeting the ASTM F1140 burst and creep requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone provides the peace of mind that all of your needs will be met. Our pricing is competitive and we offer volume discounts. Our accurate test reports are delivered quickly. When packages do not meet the requirements, we assist with finding solutions.

Summary of Flexible Package Testing Information

ASTM F1140 regulatory compliance package testing covers the ability of a flexible package to withstand internal pressurization. This test procedure is also known as package integrity testing or leak testing. ASTM F1140 package testing provides insight on package failures from a pressure differential. 

These differentials often occur during sterilization and transportation. ASTM F1140 package test method is often required for medical packages. Many food packages undergo ASTM burst and creep testing as well.

Scope of ASTM F1140 Regulatory Shock Testing

Package evaluation can occur during the package’s life cycle. This helps find failures in the lab instead of in the field. ASTM F1140 package testing must consider many factors. These include but are not limited to package size, material and sensitivity. 

Other factors include seal configuration, sensitivity and rate of air flow into the package. There are two types of testing. First, there is burst testing. Second, there is creep testing.

Significance of ASTM F1140 Burst and Creep Testing

Burst testing involves pressurizing a package until it fails. The internal pressurization is increased during testing. The test measure is the maximum pressure detected before the package fails.

The package may be tested with or without the packaged product. The package may be tested either open or closed. The failure is a visible observation. The type of failure must be noted. It could be a seal failure or packaging material failure.

Creep testing maintains a set pressure for a specific time. The testing can also result in a failure. The test measure is pass or fail.

The starting pressure is a percentage of the burst pressure. The typical starting point is 80%. This value may be raised or lowered as needed.

Package creep testing can be with or without the product enclosed. During inflation, the seal is observed. Deformations or seal breaks are noted. The test is complete once a set time is reached or the package fails.

Details of the package including the type of material and other characteristics. This can include date, time, location and test engineer. The number of packages tested and the number of failures are recorded. Any conditioning is added as well.

For the burst test, the burst pressure value and location of the failure are included. For creep testing, the internal pressure and hold time are noted. For creep to failure testing, the internal pressure and hold time are included.

Expert Pressurization Failure Resistance Package Testing

Keystone has a full lab of test equipment which permits us to provide short lead times on scheduling. Our team strives to give our customers more time and energy on product development instead of testing.

We can accommodate flexible and rigid packages of all sizes, including large pallets. In addition to ASTM F1140 testing, Keystone has a full scope of expertise including leak penetration, cold chain, and drop
